When the lamp device 920 isindoor lighting, the basically preset color may be white or a colorsimilar to white or an orange color or a color similar to an orangecolor.

When the user 910 says a predetermined trigger voice, the lamp device920 responds to the trigger voice and thus the processor 601 may beactivated and start a voice recognition function. For example, when afirst user says “Hi, Galaxy”, the lamp device 600 may recognize acorresponding voice to a trigger voice, and the processor 601 of thelamp device 600 may be converted from a sleep mode to an operation mode.When the lamp device 600 recognizes a trigger voice, the lamp device 600may perform speaker recognition and determine whether a speaker is aregistered user. According to various exemplary embodiments, a pluralityof trigger voices may be set. For example, the lamp device 600 maydistinguish a registered user based on a kind of a recognized triggervoice. The lamp device 600 may operate with at least one of a trustedvoice distinguishing method that analyzes an audio characteristic of thetrigger voice and a method of distinguishing a vocabulary of the triggervoice as a method of distinguishing a registered user based on thetrigger voice kind. For example, when a second user says “Hi, Jarvis”,the lamp device 600 may recognize a corresponding voice to a triggervoice and recognize a speaker to a second user.

With reference to FIG. 9B, when the processor 601 is activated inresponse to the trigger voice, the lamp device 920 may request a commandinput. The lamp device 920 may request a command input in a voice formor may request a command input with an operation of controlling thelighting module 921 to output a predetermined light signal. Thepredetermined light signal may be a first color or a first lightingsignal pattern set to visually notify that the lamp device 920 iscurrently in a state that requests a command input to the user 910, asshown in FIG. 10B. For example, when the lamp device 600 succeeds inboth a trigger voice and speaker recognition, the lamp device 600 mayoutput a voice request of “What would you like to do?”.

With reference to FIG. 9C, the lamp device 920 may receive a commandvoice from the user 910. For example, when the first user says “Pleaseadjust a temperature to 20° C.”, the lamp device 600 may receive acorresponding voice as a command voice.

With reference to FIG. 9D, the lamp device 920 may transmit a recognizedcommand voice to the external device 420 and receive a feedback signalfrom the external device 420. While the lamp device 920 internallyperforms a processing and stands by feedback signal reception from theexternal device 420, the lamp device 920 may control the lighting module921 to output a predetermined light signal. The predetermined lightsignal may be a second color or a second lighting signal pattern set tovisually notify the user 910 that a lamp is currently in a state thatcommunicates with the external device 1003, as shown in FIG. 10C. Forexample, the lamp device 600 may convert a recognized command voice, forexample, an audio signal of “Please adjust a temperature to 20° C.” todigital voice data and generate user account information based onrecognized speaker information. The lamp device 600 may transmitconverted digital voice data, location information of a speaker (e.g.,location information of the lamp device 920) or user account informationto the external device 420. The external device 420 may communicate withanother external device, for example, the ASR device 430 or the NLUdevice 440 to analyze the received command and output a command signalor a voice feedback signal for controlling a specific device based on ananalyzed result.

With reference to FIG. 9E, the lamp device 920 may generate voice formfeedback based on a feedback signal received from the external device420 and output the generated voice feedback. A feedback signal, forexample, a control signal and voice feedback may include a commandsignal or a voice feedback signal for controlling a specific devicebased on an execution result of natural language recognition and naturallanguage processing in the ASR device 430 or the NLU device 440. Whileoutputting voice feedback, the lamp device 920 may control the lightingmodule 921 to output a predetermined light signal. The predeterminedlight signal may be a third color or a third lighting signal pattern setto visually notify the user 910 that a lamp is currently in a state thatoutputs voice feedback, as shown in FIG. 10D. For example, the lampdevice 600 may output voice feedback of “a temperature was adjusted to20° C.” through a speaker in response to a feedback signal received fromthe external device 420. The external device 420 may output a controlsignal that controls a temperature regulator (e.g., air-conditioner,heater, boiler) simultaneously (or sequentially) with an operation ofoutputting the voice feedback.
